One particular detail of automated glass insertion requiring careful control is the start and stop of the PU application process. When the robot brings the glass around its complete path under the PU applicator and back to the start point, it is important that the overlap is carefully controlled since this also incorporates where the applicator is turned on and off.
- Measure the shape of bead overlap.
- Inspect the bead path after applying the PU glue.
- Inspect the width, height and shape of the bead in the real world scale (mm).
- Inspect the quality of bead which is not narrow, missing or overlap.
